Hi, all,
I encountered some "java.net.ConnectException: Connection refused: connect"
in the following situations:
1. Create about 350 requests to Tomcat server at the same time by sockets
2. Create about 200 requests to standalone Java ServerSocket at the same
time
It seems there is limitation of the max connections to server or
ServerSocket instance. Could you please advise me how many the max
connections are? And how to configure them in ServerSocket or Tomcat server?
Thank you in advance.

Check if your OS has TCP connection limit, check if your server can
handle that many simultaneous connections, then you can check tomcat
parameters like maxThreads

"
server?

Hi, goodbug, thank you. Could you advise where to check OS TCP connection
setting and Tomcat config file for connection?

It depends on your OS and you can google on it.
